Abstract:

Methane in biogas from anaerobic digestion of sewage sludge at Malabar Sewage Treatment Plant (STP) fuels a cogeneration system of rated capacity 2,975 kWE that helps meet the site’s electrical load of about 3,600 kWE. Low biogas flow rates limit the cogeneration system to peak loads of about 2,300 kWE in a rolling average of 1,900 kWE. Site operating costs are thus increased by the need to purchase up to 1,000 kWE of additional grid electricity at any given time. This research investigated ways to increase the supply of biogas to the cogeneration system. A literature review of anaerobic d

Abstract:

The objective of this study was to investigate the anaerobic biological treatment of an organic-bearing wastewater from a particular paper manufacturing process at laboratory scale. The process produces paper by re-pulping waste paper. Effluent from the process has a Chemical Oxygen Demand (COD) concentration of approximately 4500 mg/l with a sulphate content of approximately 300 mg SO₄²⁻/l. The upflow anaerobic sludge bed (UASB) reactor was selected for the study. Important information derived from the laboratory treatability study was: (l) the extent of COD removal possible; (2) the effluent

Abstract:

Regions with a cold winter, as in the Baltic countries, have a problem to meet the nitrogen requirement in the Urban Wastewater Treatment Directive 98/15/EC. Especially in the winter season, the temperature of the influent wastewater could arrive also below 10°C and this delays the biological processes that takes place in the wastewater treatment. With the decrease of the temperature, the efficiency of nitrogen removal in the system decreases and leads to a high nitrogen loading in the effluent.

Abstract:

Constructed wetlands are used around the world for treating domestic, agricultural, and industrial wastewater, stormwater runoff, and acid mine drainage. Plants may affect efficacy of wastewater treatment through their influence on microbial activity by creating attachment sites and releasing carbon exudates and oxygen.

High rate algae oxidation ponds (HRAOP) for domestic wastewater treatment generate biosolids that are predominantly microalgae. Consequently, HRAOP biosolids are enriched with minerals, amino acids, nutrients and possibly contain plant growth regulator (PGR)-like substances, which makes HRAOP biosolids attractive as fertiliser or PGR. This study investigated HRAOP biosolids as a starting material for a natural, cost-effective and readily-available eco-friendly organic fertiliser and/or PGRs.

Abstract:

Flow distribution chambers are devices commonly used by the water industry to distribute flows in water and sewage treatment plants. These have simple designs, and are required to operate over a range of volumetric flowrates. Many chambers surveyed (Herbath and Wong, 1997b) were found to perform poorly. They suffered from flow mal-distribution, where the flow was not distributed according to design. The most common cause of flow mal-distribution was hypothesised to be due to the presence of a pipe bend below the chamber (Herbath and Wong, 1997a, 1997b). Therefore, an experimental and numerical

Abstract:

A unidade de estudo denominada bacia hidrográfica pode ser considerada um importante agente de integração entre processos naturais e antrópicos. Através do estudo do metabolismo dos corpos hídricos, pode-se conhecer fatores que implicam nas alterações funcionais destes processos. Seguindo nesse contexto, pode-se citar a bacia do rio Piracicaba, um autêntico modelo de bacia desenvolvida, com problemas ambientais típicos de áreas impactadas. Estudos desenvolvidos pelo Projeto PiraCena, entre os anos de 1994 e 2001, confirmaram que as emissões de esgotos domésticos e industriais e as mudanças no

The National Institute of Technology Rourkela is one of the most important educational institutes in the state of Orissa with a large number of people residing in its campus consisting of a number of laboratories of various departments, residential units, academic blocks and number of hostels. A study on domestic waste water characterization has been performed followed by the design of sewage treatment plant. The present study involves the analysis of pH value, total solids, total suspended solids,hardness, acidity, alkalinity, chloride, chlorine, BOD, DO and heavy metals such as Iron, Coppe
